(CNN) — Do not adjust your screen settings: the crazily vibrant colors of this lake in Australia are all natural.

A rare flood has transformed the country's Kati Thanda-Lake Eyre from an arid salty basin to a spectacular, watery oasis -- a striking spectrum of colors, from aquamarine blue to rose pink and bright white.

The salt dilutes the water and causes algae to grow, creating the colors in the water.

Water only floods the desert lake -- which is the lowest point on the continent -- every three to 10 years. It becomes completely flooded only three times every 160 years.

The reason for the multi-colored hue? The salt dilutes the water and causes algae to grow.
